Abstract

Centrifuge apparatus includes a timing and control mechanism including a piston (10) to which is attached a cam (39, 51) having cam surfaces (5) which interact with flexible tubing (36) to control the rate of flow of blood through the tubing. The velocity of the piston (10) in the centrifugal force field of rotor (34) is determined by the resistance to flow of a viscous oil which the piston displaces with cylinder (12). The movement of the cam (39, 51) is, therefore, a measure of the magnitude and duration of the centrifugal force acting to process the blood.
